Mistake Messages

General advice: Most messages requite yous a choice of Quit and Goto. If it�s available, always choice Goto: the TI-83/84 will prove yous the exact spot where it found something incorrect. That�due south normally enough of a inkling that you can effigy out what�s incorrect.

�Syntax�

Printing [two] for Goto and recheck your equation on the Y= screen.

Make certain you pressed the [X,T,θ,n] key for 10 and non the [�] times central. Too, brand sure you lot distinguished between the minus fundamental [−] and the change sign cardinal [(-)]: the change sign key makes a shorter minus sign than the minus key.

�Window Range�

Press [1] for Quit and then press [WINDOW].

Brand certain your Xmax is greater than Xmin and Ymax is greater than Ymin.

�Dim Mismatch�

Are yous doing a scatterplot?

Press [Y=] and check that only ane of Plot1, Plot2, Plot3 is highlighted.

So printing [second] [STAT PLOT] followed by the number of the agile plot. ([STAT PLOT] is the shifted [Y=] primal.) Check which list numbers are mentioned.

Press [STAT] [ENTER] and make sure that yous have equal numbers of entries in the two lists.

Are you doing regression analysis?

Notation the two lists mentioned in your regression command, LinReg(ax+b) or similar. Press [STAT] [ENTER] and make sure that y'all take the aforementioned number of entries in the two lists, at least ii rows.

Are you doing anything else?

Press [1] for Quit and then printing [Y=]. Make sure that there are no highlights on Plot1 Plot2 Plot3 at the top of the screen. If one is highlighted, cursor to it and printing [ENTER] to deactivate it.

�Invalid Dim�

This bulletin has several possible causes.

• If you get this when making some kind of plot, you probably forgot that y'all take one of Plot1 Plot2 Plot3 turned on, and information technology refers to two lists that don�t have the same length. The cure is to press [Y=] and turn off the unwanted plot.
• If yous�re really doing something that needs lists, such every bit a regression, but your lists don�t have the aforementioned length, y'all get this bulletin. Printing [STAT] [1] and cheque your lists.
• Yous likewise get this message when yous give the TI-83 a list or matrix where information technology expected a variable or number, or vice versa. For instance, on the STAT PLOT screen, you may mean to press [2nd] [L1] but if you miss the [2nd] yous really type a Y. In the same fashion y'all might type a Z where you intend to type L2.
• Karl Wein offers another possibility. Y'all tin create a list called L1, but that is not the aforementioned as the predefined list called L1 (notation the small-capital L), and of course similarly for lists 2 through 6. If yous accidentally delete a predefined list from the editor, make sure to bring it back with the SetUpEditor control.

In general, when you lot see this message you lot demand to check carefully through what you�ve washed to make sure that you used lists where yous were supposed to, and nowhere else.

�ERR:Version�

A TI-83 (non Plus or Silver) is trying to receive something that information technology can�t handle. If what you�re trying to transfer is a program, these features work in the TI-83 Plus and all afterward TI-83s and TI-84s, but not in the original TI-83:

• archiving operations
• ii-character labels that start with a letter
• whatsoever lower-case text in strings
• the Greek letters ρ (rho) and σ (sigma) in strings, but the statistics variable σx can be used

�ERR:DOMAIN�

You�ve passed an incorrect argument to a function, such as cos^-1(2) or pxl-on(160,160).

List Troubles

It�s like shooting fish in a barrel to hibernate 1 without intending to, just by pressing the [DEL] key while positioned on a cavalcade head.

To bring back L1 through L6 in that club, press [STAT] [5] [ENTER]. This runs the SetUpEditor command; you volition not lose any numbers from any lists.

I tin can�t clear the numbers from a list.

Use the pointer keys to motion to the cavalcade heading, not the start number of the list. And then printing [Clear] [ENTER]. All the numbers from the list volition be erased, and the cursor will move to the first row and so that you can begin entering numbers.

I left out a number from my list.

No, you lot don�t have to re-enter the whole list. Use the arrow keys to motility to the number just after where the missing number should go. Press [2d] [INS] (the shifted [DEL] key) and a space volition open in the list.

Graphing Troubles

Are you plotting specific points?

Press [ZOOM] [ix], which is ZoomStat. That tells the TI-83/84 to adjust the window to show your points or histogram with maximum item.

Are you plotting 1 or more than functions?

If you don�t encounter your function graph anywhere, your window is probably prepare to a region of the xy plane the graph just doesn�t happen to go through. Depending on the function, one of these techniques will piece of work:

• ZoomFit is a good starting time attempt. Printing the [ZOOM] button, then [0] (null). (Thanks to Marilyn Webb for this proposition.)
• You can attempt to zoom out (like going higher to see more of the plane) past pressing [ZOOM] [three] [ENTER]. If you need to, press [ENTER] again to zoom out further.
• Finally, you can directly adjust the window to select a specific region. Set Xmin and Xmax and then that they include the x domain you lot�re interested in, and Ymin and Ymax to include the y range you lot want to see.

Are y'all plotting a histogram?

Press [WINDOW]. Set the Ten�s in terms of your course limits, as follows:

• Xmin = one class width less than the smallest course mark
• Xmax = one course width more than the largest class mark
• Xscl = the class width

Set up the Y�south in terms of your frequencies, namely:

• Ymin = 0
• Ymax = the highest frequency (if information technology�s a relative frequency histogram, you tin employ 1)
• Yscl = some convenient fraction of Ymax

Are you plotting a distribution using ShadeNorm?

Delight see that section of this page.

My screen is covered with horizontal or vertical lines.

This sometimes happens after zooming, or if you manually change some window parameters. What happens is that the tick marks are and so closely spaced that they merge together visually.

Press [WINDOW] and adjust the Xscl or Yscl or both. Tick marks will appear every Xscl units left and right, and y'all want that to be a reasonable fraction of the range between Xmin and Xmax. Tick marks will announced every Yscl units up and down, and yous want that to exist a reasonable fraction of the range betwixt Ymin and Ymax.

My screen is completely dark, every pixel filled in.

This means both your Xscl and Yscl values are too pocket-sized. Fix this on the WINDOW screen, every bit explained in a higher place, under My screen is covered with horizontal or vertical lines.

At that place are no tick marks on my graph.

Is your grid turned on?

Press [2d] [FORMAT] (the shifted [ZOOM] key) and verify that GridOn is highlighted. If non, cursor to information technology and press [ENTER].

Cheque your X and Y scales.

Press [WINDOW] and look at Xscl. Information technology should be greater than 0 and less than the range from Xmin to Xmax. For instance, if Xmin is −twenty and Xmax is 20, the range is twoscore and you might want Xscl to be 2, five, or 10.

Also on the WINDOW screen, look at Yscl. Information technology should be greater than 0 and less than the range from Ymin to Ymax. For instance, if Ymin is −x and Ymax is 10, the range is twenty and you might want Yscl to be 1 or 5.

Printing [Y=]. Look at Y1=, Y2=, and and so on. Cursor to the equal sign for each unwanted function, and press [ENTER]. Y'all�ll need to cursor down to examine Y8=, Y9=, and Y0=, because the Y= screen shows just seven functions at a time.

Press [GRAPH] to redraw the graph.

I can�t graph more than than i equation at a time.

Are there funny arrows at the left of your Y= screen?

The illustration and solution are courtesy of Jesse Phillips, who cites a page from the Texas Instruments back up site that has since been removed by TI for some reason:

In order to select boosted graphs, the Transformation Graphing App will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus Family. Uninstalling the App does non erase it from the calculator, it disables it from interfering with the normal graphing modes. Beneath are the steps to successfully uninstall the App.

• Press [APPS] cardinal
• Select Transfrm from the menu
• Press ane:Uninstall

My normal distribution from ShadeNorm looks wrong.

Is likewise much shaded in for the limits you set?

You demand to clear each drawing earlier making the next. Locate Describe equally the shifted [PRGM] key near the centre of the keyboard. Press [2nd] [Depict], then [1] to paste ClrDraw to the home screen, then [ENTER].

Repeat your ShadeNorm command.

Does the distribution not appear at all, or only in office?

Y'all need to prepare your window parameters. Press [WINDOW] and so set them as follows. (The numbers in parentheses are for a standard normal distribution, with mean=0 and standard deviation=1, where you specify only two parameters to ShadeNorm.)

• Xmin = mean minus 4 standard deviations (For standard ND, apply -4.)
• Xmax = mean plus iv standard deviations (For standard ND, employ iv.)
• Xscl = standard deviation (For standard ND, use 1.)
• Ymin = 0
• Ymax = 0.four divided by standard deviation�retrieve y'all can enter the expression and allow the TI-83/84 do the arithmetic for you (For standard ND, employ 0.4)
• Yscl = 0.i divided by standard difference (For standard ND, use 0.1)

After setting the window parameters, press [2nd] [QUIT] to render to the dwelling house screen, so [2d] [ENTER] [ENTER] to re-execute the ShadeNorm control.

Other Troubles

Many TI-83/84 owners don�t realize that the dissimilarity is adjustable. Here�s how:

1. Press and release the gold [2d] button. Verify that the blinking up pointer appears in the display.
2. Press and hold the blue up or downward pointer key to increment or decrease contrast, until the display is to your liking. Be alert: the display will change apace.

The reckoner will remember your contrast setting; yous don�t take to adapt information technology every time you turn the calculator on.

Where�due south the correlation coefficient?

You�ve executed a regression from the STAT CALC menu. Yous go the slope and intercept all right, but where are r and r�?

For some reason, your TI-83/84 comes from the factory configured not to brandish correlation coefficients. You need to make a one-time way setting and then that these are displayed in future regressions:

1. Press [2nd] [CATALOG] (the shifted [0] key).
2. To move to the beginning of the D�south, press the [x−1 ] key. (A dark-green D is printed above that primal. Practice non printing the green [Alpha] key first, because the CATALOG command automatically puts the TI-83/84 in alpha style.)
3. Use the arrow keys to movement to DiagnosticOn.
4. Press [ENTER] to select the command, and [ENTER] again to execute information technology.

You don�t need to re-enter your regression command. Just press [2nd] [ENTER] and [2nd] [ENTER] again to recall it, and then [ENTER] to execute it.
